Leptospirosis is known to cause abortions in pregnant sows. Is this statement true or false?

The statement is true. Leptospirosis is a bacterial infection caused by the Leptospira species, which can indeed lead to reproductive issues in swine, including abortions in pregnant sows. The bacteria can invade the uterine tissues and affect the fetus, leading to various complications such as stillbirths or, as mentioned, abortions.

In swine farming, leptospirosis poses a significant risk, particularly because the infection can be transmitted from one animal to another through urine or contaminated environments. Pregnant sows are particularly susceptible to the negative impacts of this disease, which can result in considerable economic loss. Thus, it's important for swine producers to be aware of leptospirosis, its transmission, and its effects on breeding stock to implement adequate preventive measures.
